mine comes on after awhile of driving. what was the cause of this anybody know exactly

 

On mine, the lights go on as I start driving too..

 

i've had that same problem too. after i installed my fuel pump. i would drive and all 3 ACD lights would come on. i did the same thing pulled over and turned the car off and on. but i didnt have factory HID. it doesnt do it anymore. it was kinda weird.

 

car suffers from a pathological ACD fibbing issue-its quite normal in models stemming from the Evo community
ACD fluid running low?..i know it needs servicing from Mitsu with their "specialized" tool.

 

It's either a short or in need of new diff fluid, same thing happened with mine a year ago.
